By means of atomic absorption spectrophotometry, the authors determined the lead content in vegetable, fruit and soil samples from the environments of a lead-smelting plant. The lead values obtained were some 10- to 100-fold higher than those found normally. The mean lead content in vegetables varied from 2 to 150 p.p.m. in dry matter; that in fruits, from 4 to 35 p.p.m. Lead concentrations ranging from 575 to 2900 p.p.m. were detected in the soil samples. The mean lead content in the atmosphere was between 0.62 and 0.95 mug/m3 (maximum value 12 mug/m3). From these data it was calculated that the total resorption of lead from vegetables, fruits, potatoes and air varied from 0.04 to 0.49 mg/day in the territory under investigation. To protect the population against increased intake of lead, it is recommended to abandon individual and commercial vegetable and fruit growing, especially leaf vegetables. Since the contamination of the soil persists for generations, the authors discuss its replacement by non-contaminated surface soil.
作者通过原子吸收分光光度法测定了铅冶炼厂周边环境中蔬菜、水果和土壤样本中的铅含量。所获得的铅含量值比正常情况下高出约10至100倍。蔬菜中铅的平均含量在干物质中为2至150 ppm；水果中的铅含量为4至35 ppm。在土壤样本中检测到的铅浓度范围为575至2900 ppm。大气中的铅平均含量在0.62至0.95微克/立方米之间（最大值为12微克/立方米）。根据这些数据计算得出，在所调查区域内，蔬菜、水果、土豆和空气中铅的总吸收量为每天0.04至0.49毫克。为保护居民免受铅摄入量增加的影响，建议放弃个人和商业性蔬菜及水果种植，尤其是叶菜类。由于土壤污染会持续几代人，作者讨论了用未受污染的表层土壤进行替换的问题。
